The power system quality and reliability depend on many factors; one of the most important terms is the Load Frequency Control (LFC). The goal of the LFC is to balance the power outputs of the generation to induce the varying load demands with zero variation in the frequency. PID controller contains three parameters which have all the necessary dynamics to eliminate the oscillation, increase the signal control, lead the error approach to zero and fast response on changing the controller input, especially peak undershoot, overshoot and settling time. This study presents the use of one of the optimization methods to optimize the parameters of the PID controller, which controls the four-area interconnected power systems. The PID controller Parameters are tuned using Elephant Herding Optimization (EHO) method. A comparison among multi-methods of PID tuning via multi-disturbance values and time. The results show the advantage of the proposed method compared to other PID tuning techniques.
